Patent DE-3743771-A1 (DE)
Title: Heating-circuit distributor
Inventor: FRANKE HEINRICH
IPC: F24D3/10
Filed: 1987-12-23
Abstract: The heating-circuit distributors known hitherto have sinusoidal dividing walls between the chambers whenever they possess distributor pipes arranged in a straight line, seen over the longitudinal axis of the housing. In order, nevertheless, to arrange the distributor pipes in a straight line but also to be able to provide a straight dividing wall, it is proposed to lead the mouths of the distributor pipes, and if appropriate the mouths of the flow and return pipes, in an arc into the dividing wall and thus into the associated chamber.

Title: Electromechanical pickup for structure-borne sound
Inventor: OTT GERALD DIPL ING
IPC: A63B29/02
Filed: 1988-06-27
Abstract: High-sensitivity sensor elements for pickups for structure-borne sound are very sensitive to shock and have a pronounced directional effect, for which reason three sensor elements are provided whose main axes are perpendicular to one another. The novel pickup for structure-borne sound is intended to be insensitive to shock and as free as possible from directional effects. The single sensor element of the pickup for structure-borne sound consists of a piece of coaxial cable having a piezoelectric dielectric. One cable end is joined mechanically to the housing, and the other cable end is joined to a seismic mass. Stops and resilient elements form a safeguard against shocks. The pickup for structure-borne sound is used in devices for finding buried persons. <IMAGE>

Title: Process for improving the surfaces of mouldings of wood-based materials, extending over the side faces
IPC: B27N3/06
Filed: 1988-10-08
Abstract: Process for improving the surface of mouldings of wood-based materials, extending over the side faces, by pressing on substrate sheets containing heat-curing resins and/or heat-curing polymer films under curing conditions, a release paper being inserted between the pressing tool and the pressed assembly. The process comprises the feature that between the release paper and the pressing tool there is introduced a substance which, under pressing conditions, initially forms a flowable layer and then cures during pressing. This achieves the result that when improving mouldings in such a way that the improvement extends over the side faces, problems during pressing, such as damage to the release layer or tearing of the release paper, are avoided.

Title: Pipe connection
Inventor: PREUHSLER ALFRED ING GRAD
IPC: F16L27/02
Filed: 1989-03-13
Abstract: The invention relates to a pipe connection of two overlapping pipes (1, 4), in particular for connecting pipes forming an exhaust pipe of a motor vehicle, having a widening (3) of the externally overlapping pipe (1) in the overlap region of the pipes (1, 4) and having an articulation element (6) arranged in the overlap region between the pipes (1, 4). The object of the present invention is to provide a pipe connection of the abovementioned type which permits both a length adjustment and angular compensation of the pipes which are to be connected to one another. The object is achieved in that the articulation element (6) is designed as a ring, having an outwardly curved ball-shaped outer contour which interacts with an outwardly curved ball-shaped inner contour of the widened region of the overlapping pipe (1), and having a cylindrical inner contour for receiving the overlapped pipe (4) in the ring (6), a clamping piece (7, 8) externally enclosing the pipe connection in the overlap region. <IMAGE>
Patent DE-3908191-A1 (DE)
Title: Friction damper
Inventor: JAAG DIETER
IPC: D06F37/20
Filed: 1989-03-14
Abstract: In the case of a friction damper, particularly for a drum of a washing machine, a friction surface (13, 14) of a friction lining (12) arranged on a ram (15) bears on a counter-surface (4, 5) with a surface pressure which is smaller in the event of a short travel of the ram (15) than it is in the event of a longer travel of the ram (15). The difference in surface pressure is achieved without conically preformed components by virtue of the fact that the counter-surface is formed by at least one leaf spring strip (4, 5) clamped at least at one side. At areas distant from the clamping position, this leaf spring strip (4, 5) can be bent resiliently outwards perpendicular to the friction surface (13, 14). <IMAGE>

Title: Ventilation of under-roof space - involves gaps formed in ridge tiles and in eaves
Inventor: DURST FRANZ PROF DR
IPC: E04D13/17
Filed: 1989-05-05
Abstract: The system ensures the ventilation of the under-roof space of a sloping roof which has a roof ridge and eaves. The roof is covered with tiles which are supported on laths (2). A layer of thermal insulation is mounted below the laths (2) with a gap which forms a ventilation duct (7), between the insulation and the tiles. This duct (7) is connected at its upper end to the gap below the ridge tiles, and at its lower end to a gap below the eaves (TLEE). When the wind (W) blows through the gap under the ridge tiles the air is deflected to the duct (7) on the opposite side of the roof.  At the same time air flows into the gap (7) on the leeward side by the air flow through the ridge tiles. USE - Ventilation of roof spaces.

Title: Method and device for contactless measurement of deformations (distortions) on surfaces
Inventor: DELZER SIEGFRIED DIPL ING
IPC: G01B11/30
Filed: 1989-06-19
Abstract: In the method for contactless measurement of deformations on surfaces, a pattern made from strips of light (streamers) is projected onto the surface of a test piece and the light reflected at the surface is received at an oblique angle to the direction of projection and evaluated in order to determine the deformations. The strip image reflected at the surface is compressed essentially in the direction of the strip with the formation of a one-dimensional image. The one-dimensional image is then evaluated by detecting the intensity distribution in the longitudinal direction of the image. It is possible when using the method according to the invention to make a comprehensive assessment of the surface with respect to waviness and roughness with only one measuring step.
